Here are some render bugs that happen when anti aliasing is minimized/disabled:
Hair
renders weirdly and has black dots around it (check the eye lashes)
Water
Sun makes bright dots flicker on and off on puddles
Water flickers between different colors, usually blue green and red:
Shadows
Shadows render weirdly, especially with foliage and at distance. Shadows on foliage flicker a lot when you move.
